JR IN DALLAS

I acquired a pair of AR3's from an Estate Sale in Dallas..... They were mounted between studs in a living room and sheetrock was placed around them. There is a little paint and dust on them but cabinets other wise are pristine. The homeowner added a bracket to back to mount to a wall.... See Pics... I brought them home, hooked em up and been listening to Jimmy Buffet all day. I have NO interest in keeping them.... They sound good, but I believe they are going to need some work.. clear sound coming out of both cabinets on bass. tweeter on one is clear, other not so much... Pots move freely, but does not appear to alter sound noticeably. Serial Numbers are 07733 and 28513. I believe they are 100% original. The grills and AR 3 logos still intact. I hesitate to open, touch, them at all... I have a tendency to be a bull in a china shop. Not sure if I should lightly sand the surface paint off, or leave to next guy. Don't necessarily want to use CRAIGSLIST. Not sure how to promote them as "used, but probably need work". Also not sure what I should ask for them.... Any suggestions would be GREAT. Thanks, JR
